TECHNICAL FIELD

The present disclosure relates generally to controlled-environment facility resident communications, specifically to controlled-environment facility resident communications employing a controlled-environment facility resident communication terminal, or the like, and particularly to controlled-environment facility resident communications carried out using a docking station or the like that comprises a docking station-integral solid-surface keypad.

BACKGROUND

Portable computing devices, including tablets, laptop computers, and personal digital assistants, allow users to access many of the functions of a personal computer (PC) while facilitating freedom of movement. Portable computing devices can offer a very high level of mobility and flexibility to the user. Portable computers are generally lightweight and compact, but these devices can also be subject to certain limitations, such as smaller keyboards and displays, reduced battery storage, lack of a keyboard, mouse, or printer ability, restricted network connections, or limited memory/data storage.

Traditionally, jails and prisons have allowed inmates to contact friends and family via letters and telephone calls. More recently, jails and prisons have begun to allow inmates to use portable electronic devices, such as tablets, to facilitate contact with friends and family and for entertainment and education. It is not desirable to provide inmates with chargers or other electronics that could be used with the tablets since these devices might be used as weapons or vandalized. However, there is still a need to charge the tablets and potentially a desire to expand the capabilities of portable devices.

Traditional communication services provide residents of controlled-environment facilities (such as correctional facilities) the ability to place outbound phone calls to non-residents of the controlled-environment facility. Additionally, non-residents can typically schedule video visitation with residents (inmates) of the controlled-environment facility. Other types of communication available to controlled-environment residents include the ability to exchange email and canned text messages between residents and non-residents of the controlled-environment facility. Such communications are typically carried out using a controlled-environment facility resident communications terminal, or the like, that has a keypad, keyboard, or the like, composed of a membrane and open circuit board utilizing resistive or capacitive touch. Such traditional keypads are predominantly implemented using mechanical and electrical contact-based systems. These systems are prone to mechanical failure breaking down and consequently require expensive replacements over their lifetimes due to moving parts and dependence on electrical contact. Further, these keypads and keyboards are suspectable to damage from (sanitizing) cleaning products, such as bleach, ammonia, etc.

For convenience of explanation, the various examples discussed herein are presented in the context of correctional facilities or the like. For instance, in some of the embodiments discussed below, a controlled-environment facility may be referred to as a correctional facility, jail, or prison, and its residents may be referred to as inmates, prisoners, arrestees, or detainees. It should be understood, however, that the systems and methods described herein may be similarly applicable to other types of controlled-environment facilities and their respective residents.

FIG. 1A is a diagram of a docking station according to an example embodiment and FIG. 1B is another diagram of a docking station according to an example embodiment. Docking station 101A has an area 102 adapted to hold a personal computer wireless device 103A. Area 102 may be a shelf, ledge, lip, slot, frame, detent, bracket, or other structure that is configured to hold personal computer wireless device 103A in or on docking station 101A. As shown in FIG. 1B, docking station 101B, and/or personal computer wireless device 103B, may be configured such that docking station 101B holds or supports personal computer wireless device 103B in a landscape orientation, or as illustrated in FIG. 1A configured to hold the personal computer wireless device in a portrait orientation. Docking stations 101A and 101B are referred to herein as “docking station 101” (and 201 and 306, below), and personal computer wireless devices 103A and 103B are referred to herein as “personal computer wireless device 103” (and 202 and 305, below). Although area 102 is shown as a recessed area in FIGS. 1A and 1B, it will be understood that in other embodiments personal computer wireless device 103 may be positioned above docking station 101 (e.g., the bottom of personal computer wireless device 103 sitting on the top of docking station 101) or may be held in a position external to docking station 101 (e.g., on a ledge or bracket extending from the side of docking station 101). Personal computer wireless device 103 may be held in position by gravity (e.g., personal computer wireless device 103 sitting on a shelf or surface of docking station 101) and/or by a more secure method (e.g., using VELCRO®, magnets, straps, rails, or other fasteners or structures). Additionally, adapter sleeves or rails may be used to ensure alignment of the personal computer wireless device 103 relative to docking station 101, which would allow docking station 101 to be used with different size personal computer wireless devices.

Docking station 101 provides a direct or indirect electronic connection to personal computer wireless device 103. In some embodiments, docking station 101 has a connector 104 a adapted to engage a connector 104 b on personal computer wireless device 103. Connectors 104 a, b may be, for example, USB (type-A, -B, or -C, mini, or micro), Lightening, RS232, RJ11, RJ45, or any other standardized or proprietary connectors. Alternatively, or additionally, docking station 101 and personal computer wireless device 103 may be linked using pogo pins or probes 105 a that engage contacts 105 b. Probes 105 a may have a fixed length or may be spring-loaded. Any number of probes 105 a and contacts 105 b may be used and may be arranged in any appropriate configuration or format (e.g., all in one line, distributed in a matrix or array, etc.). The male and female side of the connectors 104 a, b or probes 105 a, b may be located on either docking station 101 or personal computer wireless device 103. Connectors 104 a, b and/or probes 105 a, b may be used to pass data (in digital or analog form), audio, and/or power between docking station 101 and personal computer wireless device 103. If both connectors 104 a, b and probes 105 a, b are present, they may pass data, audio, and/or power between docking station 101 and personal computer wireless device 103 at the same time (i.e., simultaneously). Alternatively, one of these links might be dedicated to one type of connection (e.g., power) and the other link used for other connections (e.g., data and/or audio).

In other embodiments, docking station 101 and personal computer wireless device 103 may be communicatively coupled via a radio frequency (RF) interface, such as connections based on Wi-Fi Li-Fi, Bluetooth, ZigBee, WiMAX, Near-field communication (NFC), or other communication protocols or standards. The RF connection may be used to pass data between docking station 101 and personal computer wireless device 103 at the same time (i.e., simultaneously) as connectors 104 a, b and/or probes 105 a, b. Alternatively, the RF connection may be the only data link between the devices. Personal computer wireless device 103 may also communicate with other devices, such as a wireless access point or router (not shown) via an RF connection.

In some embodiments, docking station 101 may provide wireless power to personal computer wireless device 103 using time-varying electric, magnetic, or electromagnetic fields. Wireless power transmission provides power to personal computer wireless device 103 without requiring a direct connection (e.g., connectors 104 a, b or probes 105 a, b). Wireless power transmission may be non-radiative or radiative. In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes. In far-field or radiative techniques, power is transferred by beams of electromagnetic radiation, such as microwaves or laser beams. Docking station 101 and personal computer wireless device 103 may be configured with the appropriate circuitry (e.g., coils, armatures, or antennas) to support either non-radiative or radiative wireless power transmission.

Personal computer wireless device 103 may optionally have a camera 106, microphone, 107, and speakers 108 that allow a user to interact with the personal computer wireless device 103. Personal computer wireless device 103 has a display screen 109 that may provide an interface to application programs, which may be selected by touching application icons and/or using a keyboard. For example, personal computer wireless device 103 may have a physical keyboard attached and/or may have a touch-sensitive screen that can display a virtual keyboard and/or one or more application icons. Display 109 may be any suitable electronic display such as a liquid crystal display (LCD), thin-film-transistor liquid-crystal display (TFT LCD), light-emitting diode (LED), touchscreen display (e.g., resistive, capacitive, etc.), or the like. Docking station 101 may also provide a tiltable camera 110, microphone 111, and speakers 112. Upward and downward tilting camera 110 may, in accordance with embodiments of the present systems and methods, be associated with video communications, or the like, discussed below, or with the personal computer wireless device when the personal computer wireless device is held in the docking station. Docking station camera 110 may tilt at an angle appropriate to conform with the Americans with Disabilities Act (ADA), or the like. By way of example, such an angle of tilt of camera 110 may be fifteen degrees, plus-or-minus (i.e. upward or downward from horizontal). Speakers 108 and 112 may be permanently affixed devices on personal computer wireless device 103 and docking station 101, or speakers 108 and 112 may be attached (e.g., by wire or wirelessly) as headphones or earbuds. Docking station 101 also has a handset 113 that provides a microphone and speaker interface. Docking station may also include lights 114 that can be used to illuminate the user who is in front of camera 110.

In accordance with embodiments of the present systems and methods docking station 101 includes integral metal surface 115, which, in accordance with some embodiments may be part of a casting (e.g., diecast metal (aluminum), sheet metal, or the like) defining generally all of housing 116 of docking station 101. Integral, solid-surface keypad 117 may be defined in, and by, surface 115 of docking station housing 116 (e.g., printed, embossed, braille imprinted, or the like). In accordance with embodiments of the present systems and methods, docking station 101 may include electronic (voice, video, etc.) communications functionality, such as may be employed when personal computer wireless device 103 is not held in the docking station using keypad 117 and handset 113, or alternatively speaker(s) 112 and microphone 111, through controlled-environment facility communication processing system data, electronic communications support, as discussed below.

When personal computer wireless device 103 is coupled to docking station 101, the camera 110, microphone 111, speakers 112, and/or handset 113 on the docking station may be used instead of, or in place of, camera 106, microphone, 107, and/or speakers 108. Cameras 106, 110 may be any suitable imaging device, such as a video camera or webcam equipped with charge-coupled devices (CCDs), complementary metal-oxide-semiconductor (CMOS) active pixel sensors, etc. It will be understood that the size, positioning, orientation, and type of devices shown as connectors 104 a,b, probes 105 a,b, camera 110, microphone 111, speakers 112, and handset 113 in FIGS. 1A and 1B are merely illustrative and that any appropriate replacement components may be used to provide the same functionality and operational capability as these examples. In another embodiment, for example, camera 110 may be embedded within docking station 101 in a form that has a lower profile and that is less exposed to damage or vandalism. Additionally, docking station 101 may have multiple cameras 110 to support facial recognition technology for biometrics or other applications.

Personal computer wireless device 103 may have limited input/output capabilities, such as having speakers 108 and display 109 only (i.e., no microphone or camera). This configuration allows a user to watch movies, listen to music, read e-books, and read/write messages on personal computer wireless device 103, but would not allow the user to participate in telephone calls or interactive video conferences. However, when personal computer wireless device 103 is coupled to docking station 101, then camera 110, microphone 111, speakers 112, and handset 113 are available to the user so that communications applications on personal computer wireless device 103 can be accessed to make telephone calls or join video conferences. Speakers 112 may be used as a microphone in other embodiments, which would eliminate the need for a separate microphone 111. Additional embodiments may include multiple microphones 111 to provide far field voice monitoring capability. This would enable docking station 101 to clearly capture voice inputs in high ambient noise environments and/or to provide enhanced voice biometrics capability. In other embodiments (not shown), docking station 101 may also include a keyboard and/or may provide access to other network devices, such as a printer, scanner, storage drive, or the like.

Although the examples described herein refer to a personal computer wireless device 103, it will be understood that docking station 101 may provide data and power to a personal computer wireless device, such as any portable electronic device or computer-based system. Examples of personal computer wireless devices that may be used with docking station 101 include a tablet computer, laptop computer, smartphone, personal digital assistant, media player, e-book reader, or the like. In one embodiment, personal computer wireless device 103 may be specially adapted and/or approved for use by residents of a controlled-environment facility. For example, in a correctional institution (e.g., a jail or prison), personal computer wireless device 103 may be “stripped-down,” particularly from the standpoint of the operating system capabilities, the application programs (apps) that are provided or allowed on personal computer wireless device 103, and/or the connectivity afforded personal computer wireless device 103. In a correctional facility environment, docking station 101 may have a hardened case and may be mounted on a wall or in a kiosk in location available to multiple users having personal computer wireless devices. Likewise, in some such embodiments, personal computer wireless device 103 may be a tablet computer, smartphone, personal digital assistant, media player, e-book reader, or the like of a non-resident visitor to a controlled-environment facility, such as a correctional facility, or a non-resident visitor to a remote visitation center associated with such a controlled-environment/correctional facility. Therein, the non-resident visitor may make use of docking station 101 located in a visitor area, the visitor center, etc., for charging their personal computer wireless device 103, and/or for carrying out a video visitation with a controlled-environment/correctional facility resident/inmate using the non-resident visitor's docked personal computer wireless device, in accordance with embodiments of the present systems and methods. Additionally, or alternatively, in such a visitor center or controlled-environment facility visitor area, a personal computer wireless device may be provided to a non-resident visitor to use in a video visitation with a resident/inmate.

Personal computer wireless device 103 may be adapted to connect only to a network provided by the controlled-environment facility and/or only in certain locations within the controlled-environment facility. Such connectivity may be limited by controlling the availability of wireless/RF access to certain areas through the placement of wireless access points or adjusting antenna directionality of such wireless access points. Personal computer wireless device 103 may have a limited number of pre-installed applications on the device, such as communications, telephone calling, video conferencing, or video visitation applications. Installation of further applications on the device may be forbidden (e.g., prevented by the device's operating system) and/or restricted (e.g., requiring permission from an administrator).

A user may be prompted to provide a personal identification number (PIN), biometrics (e.g., facial recognition, fingerprints, finger geometry, iris recognition, vein recognition, retina scanning, voice recognition, or DNA matching) or other identifying information to access personal computer wireless device 103. Either docking station 101 and/or personal computer wireless device 103 may have a biometric sensor (not shown) to authenticate user biometric information.

As noted, in accordance with some embodiments of the present systems and methods a communication system may include a communication processing system configured to support data, voice and video communications and a docking station coupled to the communication processing system. Therein, the docking station may also act as a controlled-environment facility communications terminal, such as by providing electronic communication functionality, such as Publicly Switched Telephone Network (PSTN) and/or Voice over Internet Protocol (VoIP) communication functionality, to a user employing an integral, solid-surface keypad 117 defined in, and by, surface 115 of docking station housing 116, when personal computer wireless device is not held in the docking station. For example, docking station 101 may be coupled to a network of pairs of low-voltage wires to provide PSTN electronic communications functionality via such controlled-environment facility communication processing system data, electronic communications support. Alternatively, or additionally, the communications functionality provided by docking station 101, when personal computer wireless device 103 is not held in docking station 101 may be VoIP functionality, wherein keypad 117 is configured to initiate and/or otherwise enable VoIP call functions, and/or the like. Session Initiation Protocol (SIP) VoIP communication functionality may implement client and server functions of a SIP user agent and provides call functions, such as dial, answer, etc. The same (single) pair of the low-voltage wires providing the aforementioned PSTN and/or VoIP communication functionality may also provide electrical current sufficient to power personal computer wireless device 103 and/or charge a battery in the personal computer wireless device, when personal computer wireless device 103 is held in docking station 101, as described below.

Keypad 117 may include, beyond zero to nine digit keys, separate loudness control 118, which may, such as in accordance with Americana's with Disabilities Act (ADA) requirements, or the like, offer there or move volume settings for phone calls carried out using handset 113 or microphone 111 and speaker(s) 112. In accordance with such embodiments, keypad 117 is used to initiate, or otherwise enable, call functions. Further to wit, the keypad may comprise raised numbers and/or letters, braille numbers and/or letters, etc. (not illustrated, for purposes of clarity). Further, keypad 117 may, in various embodiments, provide haptic feedback to activation/selection of a key of the keypad, such as by touching of the key, such as, for example, in further ADA compliance. This feedback may be vibration, a responsive (counter) impact (emulating a button push), an audible sound, illumination of a light associated with the keypad or digit, or the like.

Solid-surface docking station integral keypad 117 may employ ultrasonic transducers deployed in conjunction with the keypad, such as mounted on a back surface of docking station housing surface 115, to detect contact with the keypad by a finger, prosthetic, or the like, when the personal computer wireless device is not held in docking station 101. For example, the ultrasonic transducer may each be part of an ultrasonic transducer-based (low power) sensor, or sensor array deployed in conjunction with keypad 117 to detect touch and/or force through docking station housing surface 115 in a particular location indicated by keypad 117 for input of a number, letter, special character, or the like. These ultrasonic keypad sensors may provide highly localized touch sensing through the relatively thick (up to one inch) surface 115 of docking station (diecast metal (aluminum), sheet metal, or the like) housing 116 in an “always-on-mode,” providing wake-on-touch sensing, such as by powering on communications functions of docking station 101, and accepting input of the touched keypad digit or function, in response to touch of the keypad digit or function (when the personal computer wireless device is not held in docking station 101 and keypad 117 is consequently accessible). Such ultrasonic transducer-based embodiments provide contactless sensing technology that offers a durable keypad implementation that is resistant to harsh environments and liquid intrusion.

In accordance with other embodiments of the present systems and methods, keypad 117 may be an inductive touch keypad with non-moving inductive touch buttons on flat (metal) surface 115 that relies on deflection of surface 115. Inductive sensing used in conjunction with such embodiments is a contactless sensing technology that offers a durable keypad implementation that is resistant to harsh environments and liquid intrusion, as well. Therein, inductive touch buttons defined in medal surface 115 may be used in conjunction with an inductance-to-digital converter, or the like. As noted, inductive touch buttons may be defined in integral metal surface 115, which, in accordance with some embodiments may be part of a casting (e.g., diecast metal (aluminum), sheet metal, or the like) defining generally all of housing 116 of docking station 101. In such embodiments, the inductance-to-digital converter, or the like, detects deflections that occur when a button is pressed. In accordance with embodiments of the present systems and methods, even a light force applied to a button, results in an inner surface of metal surface 115 deflecting toward a sensor coil deployed in conjunction with that button, such as on a Printed Circuit Board (PCB) mounted on an inside face of docking station surface 115, without the metal contacting the sensor. However, the small amount of deflection from the press causes a shift in the sensor inductance that can be detected by the inductance-to-digital converter, or the like, and interpreted as a button press, which may then trigger button acknowledgment through haptic vibration, button press emulation impact, sound (e.g., audible beeping), illumination of a light associated with the keypad or digit, or the like, to give the user an indication of a valid button press. Further, in various embodiments, this sensing of the deflection of the metal surface, and thereby a button press may be force-dependent.

In accordance with some embodiments, docking station 101 may be configured to disable call functions of the docking station when personal computer wireless device 103 is held in the docking station. Conversely, in accordance with further embodiments, communication in progress on personal computer wireless device 103 may be swapped to the docking station phone functionality upon the personal computer wireless device being placed in or on the docking station, by handoff of call signaling, such as VoIP/SIP signaling, from the personal computer wireless device to the docking station.

Additionally, in accordance with such, or other, embodiments, another docking station, a PSTN phone or an independent VoIP phone may be coupled to a communication network, via docking station 101, and (a) further docking station(s), further PSTN phone(s) or further independent VoIP phone(s) may be coupled to the communication network, via this other docking station, the other PSTN phone or the other independent VoIP phone.

Implementation of an integral, solid-surface keypad defined in, and by, one surface portion of a docking station diecast (metal (aluminum)), sheet metal, or the like, housing, in accordance with various embodiments of the present systems and methods may provide a keypad that can be sanitized through the use of spray disinfectants and the like, without risk of damaging underlying circuitry, or the like, such as is a concern with membrane and open circuit board based keypads.

FIG. 2 is a block diagram illustrating components of docking station 201 according to an example embodiment. Docking station 201 may be used to provide an interface between personal computer wireless device 202 and a remote communication network 203 via network 204. Docking station 201 may function to communicate information, such as data packets and/or speech signals, between personal computer wireless device 202 and communication network 203. For example, in accordance with some embodiments of the present systems and methods docking station 201 may, when the personal computer wireless device is not held in the docking station, provide electronic communication functionality to a user employing a keypad, speaker(s), and a microphone, using controlled-environment facility communication processing system data, electronic communications support. Additionally, or alternatively, docking station 201 may transfer power from communication network 203 to personal computer wireless device 202.

Docking station 201 has a network interface 205 adapted to connect to network 204. In one embodiment, network 204 is a network of single pairs of low-voltage wires, such as telephone wires (e.g., a twisted pair of copper wires), alarm system wires, intercom wires, etc. Each pair of low-voltage wires may terminate in the form of a telephone jack, connector, or the like for connection to network interface 205. In other embodiments, network 204 may be an Ethernet network that is connected to network interface 205 by a Cat 5 cable or other communication or data network that is connected to network interface 205 by a coaxial or other cable. Further, in accordance with some embodiments of the present systems and methods the docking station may be coupled to communication network 203 over a plurality of pairs of low-voltage wires, such as an Ethernet cable. At least some of such a plurality of pairs of low-voltage wires may provide a data connection, such as for VoIP call functions, PSTN call connectivity, and/or the like, and at least some of the plurality of pairs of low-voltage wires have an electrical current sufficient to power the personal computer wireless device, and charge its battery. Such power may be provided over these pairs of Ethernet cable wires in accordance with a Power over Ethernet (PoE) protocol. In some other, or further, embodiments, network 204 may be, or at least include, a wireless network, such as a wireless local area network (WLAN). In such embodiments, network interface 205 may provide a wireless interface for connecting to WLAN 204, rather than, or in addition to, the above discussed wire pair(s) interface.

In some wired embodiments, communication network 203 may include an extended signaling and electrical powering system that provides electrical power and/or communications to docking station 201 over network 204. An example extended signaling and electrical powering system 203, 204, 205 is described in U.S. Pat. No. 8,594,314, titled “Extended Signaling System and Method,” the disclosure of which is hereby incorporated by reference herein in its entirety. An extended signaling and electrical powering system is described in more detail below in connection with FIG. 3 . The extended signaling and electrical powering system in network 203 may enable a source of electrical current to deliver an amount of current over the same existing wiring that is higher than ordinarily provided to enable telephone use over a single pair of low-voltage wires. The extended signaling and electrical powering system in network 203 may also enable the exchange of telephony and non-telephony signals (e.g., data) between communication system network 203 and docking station 201. As such, although a typical 48 VDC powered telephone line is only sufficient to provide about 25 mA of DC current to a local telephone or device, an extended signaling and electrical powering system may allow the same low-voltage level to deliver a current in excess of 25 mA using the same wiring while providing additional power, signaling, and data communication capabilities. As such, communications network 203 may be configured to deliver at least 40-60 mA or more current to docking station 201 (instead of the typical 25 mA current). Furthermore, communications network 203 may enable the additional current to be converted to a lower voltage but higher current, which is then made available to docking station 201 over the same single pair of wires in network 204. For example, in some implementations, communication network 203 may be capable of providing 100 mA or more current at 5V to docking station 201 over thousands of feet of standard telephone wire in addition to providing signaling channels to enable data communication services.

Controller 206 manages and controls the operation of docking station 201 in one embodiment. Controller 206 may be a microprocessor or application-specific integrated circuit (ASIC) that allows for intelligent operation of docking station 201 by executing software or firmware instructions. As noted, in accordance with embodiments of the present systems and methods, the docking station may also act as a controlled-environment facility communications terminal, such as by providing PSTN and/or VoIP communication functionality. PSTN and/or VoIP communication functionality of docking station 201 may be implemented herein by implementation of softphone software, firmware, or the like by docking station controller 206, or the like. In one embodiment, controller 206 functions as a modem to provide a Digital Subscriber Line (DSL) data connection between docking station 201 and communication network 203. In other embodiments, network 205 and controller 206 may be hardwired circuitry (e.g., filters, splitters, rectifiers, matching circuits) adapted to couple lines from network 203 to various components in docking station 201.

Docking station 201 includes a power circuit 207 that provides charging and/or operating power to docking station 201 and personal computer wireless device 202. Power circuit 207 may receive power from communication network 203 directly or under control of controller 206. In this embodiment, docking station 201 would be powered by relatively low power that is available across a single pair of wires in network 204. In some embodiments, a local power supply 208 may provide power to docking station 201 and power circuit 207 in addition to or in place of power from network 203. Power supply 208 may be a battery, an AC adapter, or any other power source that is charged, for example, by current from network 203. Power circuit 207 may provide power directly to personal computer wireless device 202 through connector 209 and/or probes 210. Additionally, or alternatively, power circuit provides power via wireless power transmitter 211 (e.g., a coil, armature, or antenna) to a corresponding wireless power receiver (not shown) on personal computer wireless device 202.

Connector 209 and/or probes 210 may provide a data connection between docking station 201 and personal computer wireless device 202. The data may comprise digital packets of varying complexity or may be analog voice and/or video signals. Additionally, or alternatively, a wireless transceiver 212 may provide a radio frequency (RF) interface (e.g., based on Wi-Fi, Bluetooth, ZigBee, WiMAX, Near-field communication (NFC), or other communication protocols or standards) and may exchange data and/or audio wirelessly between docking station 201 and personal computer wireless device 202.

Docking station 201 further includes an input/output circuit 213 that provides an interface to microphone 214 and speaker 215. Input/output circuit 213 receives audio/speech signals from microphone 214 and provides audio/speech signals to speaker 215. Microphone 214 and speaker 215 may be discrete components in docking station 201 and/or may be embodied in a handset 216. When personal computer wireless device 202 is coupled to docking station 201 via connector 209, probes 210, or wireless interface 212, handset 216 (or microphone 214 and speaker 215, individually) provide an additional or extended audio input/output for personal computer wireless device 202. In some embodiments, in place of a separate handset 216, docking station 201 may function as a speakerphone having a built-in speaker 217 and microphone 218.

In one embodiment, circuitry for enabling the functionality of handset 216, microphones 214, 218, and speaker 215, 217 is included in personal computer wireless device 202 so that these components are only operable when personal computer wireless device 202 is coupled to docking station 201. For example, signals for handset 216, microphones 214, 218, and speaker 215, 217 may be routed through connector 209 and/or probes 210 so that the components do not work when nothing is attached to the connector or probes. In accordance with embodiments of the present systems and methods, when no personal computer wireless device 202 is connected to docking station 201, handset 216, microphones 214, 218, and speaker 215, 217 may be connected to communication network 203 for, normal PSTN telephone service or connected to an intercom system, or may be used for VoIP service. Handset 216 may have loop circuit sensor 223 communicatively coupled to the speaker, and/or loop circuit sensor 224 communicatively coupled to the microphone. These loop circuit sensors are, such as through I/O circuit 213, controller 206, interface network 205 and network 204, communicatively coupled to and communication network 203.

Docking station 201 may include a biometric sensor 219 that is coupled to controller 206. Biometric sensor 219 may be used, for example, to verify and/or authenticate a user's identity using facial recognition, fingerprints, finger geometry, iris recognition, vein recognition, retina scanning, voice recognition, or DNA matching.

Other technologies may also be used to verify and/or authenticate a user's identity. For example, docking station 201 may include a radio-frequency identification (RFID) transceiver, interrogator, or reader 220 that is configured to automatically identify and track RFID tags. These RFID tags may be attached to objects or people. For example, RFID tags may be attached to tamper-detecting bracelets that are worn by users and/or attached to personal computer wireless device 202. Docking station 201 can be configured to require detection of a known user RFID tag and/or a known personal computer wireless device 202 RFID tag before allowing personal computer wireless device 202 to be used with docking station 201.

In one embodiment, docking station 201 may be required to authenticate both the user (e.g., using biometrics, RFID, a PIN, etc.) and personal computer wireless device 202 (e.g., using RFID, an electronic or digital certificate, etc.) before allowing access to communication network 203 and/or docking station 201 functionality. RFID transceiver 220 may be used to track and locate personal computer wireless device 202 whether or not they are connected to docking station 201. RFID transceiver 220 may be used with proximity (e.g., ISO 14443 air-interface protocol standard) or vicinity (e.g., ISO 15693 air-interface protocol standard) tags. Proximity RFID tags employ close coupling and need to be in close proximity (e.g., a few centimeters) to the RFID transceiver 220. Vicinity RFID tags can be read at a distance (e.g., a meter or more). When personal computer wireless device 202 has an attached vicinity RFID tag, then personal computer wireless device 202 may be detected when passing docking station 201 even if the personal computer wireless device 202 is not actually connected to docking station 201. Vicinity RFID tags may be used to inventory personal computer wireless devices and/or for finding lost personal computer wireless devices. In an alternative embodiment, the RFID tag is located on docking station 201 and personal computer wireless device 202 has an RFID transceiver that is used to provide location, identification, and authentication functions.

The applications loaded on personal computer wireless device 202 may be available for use whether or not personal computer wireless device 202 is being used by itself or is coupled to docking station 201. For example, communication applications may be used by personal computer wireless device 202 alone or in conjunction with docking station 201 (e.g., handset 216 allows a user to have a more private conversation than using the communication application on personal computer wireless device 202 alone).

In other embodiments, applications on personal computer wireless device 202 may be specifically enabled or disabled when personal computer wireless device 202 is coupled to docking station 201. For example, certain applications on personal computer wireless device 202 may be disabled when the device is coupled to docking station 201. This may be required to isolate the application and/or communication network 203 from each other. This scenario might occur when certain content on communication network 203 (or on docking station 201) should not be accessed or downloaded by personal computer wireless device 202, or when content on personal computer wireless device 202 should not be uploaded to communication network 203 (or to docking station 201). In another example, an application may require more memory than is available on personal computer wireless device 202 or may require content or functionality that is only available on docking station 201 or communication network 203 (e.g., a database, authentication operation, additional graphics processing, lock icon overlay, etc.). When personal computer wireless device 202 is coupled to docking station 201, then this application on personal computer wireless device 202 may be accessed by the user, but would be unavailable (e.g., no icon on display, grayed-out icon, an error pop up message, etc.) when personal computer wireless device 202 is not connected to docking station 201.

There may be additional applications that are stored on or that execute only on docking station 201. Memory 221 may store application software and/or data for execution or use by controller 206. When personal computer wireless device 202 is coupled to docking station 201, then this application on docking station 201 may be accessed by the user. For example, an application stored in memory 221 may be too large to store on personal computer wireless device 202 or may require more processing capability/power than is available on personal computer wireless device 202 alone or might be available only to certain personal computer wireless devices or users. An icon for the application stored or executing on docking station 201 may be shown on display 222 only when personal computer wireless device 202 is coupled to docking station 201 since that is the only time that the application can be accessed by the personal computer wireless device user.

As noted, in accordance with embodiments of the present systems and methods, a communication system may include communication network 203 configured to support data, voice and video communications and docking stations 201 coupled to the communication network, such as via local network 204. In accordance with embodiments of the present systems and methods, the docking stations not only selectively holds a personal computer wireless device and provides power and data connections to the personal computer wireless device, as discussed above, but also Docking station may include keypad sensor(s) 225 (i.e., one or more sensors, a sensor array, or the like) coupled to input-output circuit 213 and/or controller 206 and deployed in conjunction with keypad 117 to detect touch and/or force through docking station housing surface 115 in a particular location indicated by keypad 117 for input of a number, letter, special character, or the like, to-provide localized touch sensing through the relatively thick (up to one inch) surface 115 of docking station (diecast (aluminum), sheet metal, or the like) housing 116. Thereby, sensor(s) 225 are configured to initiate, or otherwise enable, PSTN and/or VoIP call functions.

In accordance with such embodiments, docking station 201 may be configured to disable such PSTN and/or VoIP call functions of the docking station when personal computer wireless device 202 is held in the docking station. In accordance with further embodiments, a VoIP communication, or the like, in progress on personal computer wireless device 202 may be swapped to the docking station VoIP communication functionality upon the personal computer wireless device being placed in or on the docking station, by handoff of VoIP signaling from the personal computer wireless device being the docking station.

Keypad sensors 225 may each be an ultrasonic transducer-based (low power) sensor, or sensor array deployed in conjunction with the keypad to monitor acoustics to detect touch and/or force through the portion of a docking station housing surface defining the solid-surface keypad, in a particular location indicated by the keypad for input of a number, letter, special character, or the like. Each such ultrasonic transducer-based sensor may include its own ASIC, or the like, with an embedded micro-controller, memory, analog converter, and/or the like, as an integral sensor or sensor array. One or more of these keypad sensors may support surface gestures for sliders, or the like, such as to provide loudness functions (rather than, or in addition to loudness control 118, or the like), etc. Such ultrasonic keypad sensors may operate conjunction with input-output circuit 213 and/or controller 206. However, processing embedded in the sensor ASIC may provide general standalone operation and direct output from the sensor to input-output circuit 213 and/or controller 206 of a user-selected digit or function. Ultrasonic keypad sensors may (each) provide highly localized touch sensing through the relatively thick (up to one inch) surface 115 of docking station (diecast (aluminum) sheet metal, or the like) housing 116 in an “always-on-mode,” providing wake-on-touch sensing, such as by powering on communications functions of docking station 201, and accepting input of the touched keypad digit or function, in response to touch of the keypad digit or function. Also, ultrasonic keypad sensors, and/or an array thereof, may provide a multi-function user interface, providing the user functionality through a series of taps, holds, swipes, etc. Ultrasonic keypad sensors may also include, or interface, such as through input-output circuit 213 and/or controller 206, haptic driver circuitry, to provide the afore described haptic feedback (vibration, impact, sound, light, etc.) for a key touch, or the like. Ultrasonic keypad sensors may also provide, and/or at least facilitate, such as in conjunction with input-output circuit 213 and/or controller 206, force sensing so as to not only determine touch, but also, levels of force (e.g., light, medium, heavy).

In accordance with other embodiments of the present systems and methods, keypad sensors 225 (e.g., a sensor array) may each comprise a sensor coil deployed in conjunction with a keypad button, on a PCB, or the like, mounted on an inside face of docking station surface 115. In such embodiments, keypad 117 may be an inductive touch keypad with non-moving inductive touch buttons defined on flat (metal) surface 115. Such embodiments employ deflection of surface 115 in conjunction with the button sensor coils and an inductance-to-digital converter, or the like. This inductance-to-digital converter, or the like, detects deflections that occur when a button is pressed, without the metal contacting the sensor. However, the small amount of deflection from the press causes a shift in the sensor inductance that can be detected by the inductance-to-digital converter, or the like, and interpreted as a button press by input-output circuit 213 and/or controller 206, which may then trigger button acknowledgment through haptic vibration, button press emulation impact, audible (beeping) sound, illumination of a light associated with the keypad or digit, or the like, to give the user an indication of a valid button press. Further, in various embodiments this sensing of the deflection of the metal surface, and thereby a button press may be force-dependent.

Additionally, in accordance with such, or other, embodiments, another docking station, a PSTN phone or an independent VoIP phone may be coupled to communication network 203, via docking station 201 (e.g. via network interface 205), and (a) further docking station(s), PSTN phone(s) or independent VoIP phone(s) may be coupled to the communication network, via this other docking station, the PSTN phone or the independent VoIP phone.

FIG. 3 is block diagram of an example of a system configured to provide communication services to a controlled-environment facility according to some embodiments. As shown, communication processing system 301 may provide telephone services, videoconferencing, and/or other communication services to a controlled-environment facility 300. The communication processing system 301 may be implemented by one or more computer systems, an example of which is described below. In some cases, communication processing system 301 may be located in or remote from the controlled-environment facility 300. In some cases, communication processing system 301 may be centrally or remotely located with respect to one or more controlled-environment facilities and/or may provide communication services to multiple controlled-environment facilities. More generally, however, it should be noted that communication processing system 301 may assume a variety of forms, and may be configured to serve a variety of facilities and/or users, whether within or outside of a controlled-environment facility.

One or more resident communication devices are in the controlled-environment facility 300. In the illustrated example, the controlled-environment facility 300 includes one or more telephones 302 (302 a, 302 b, etc.) one or more controlled-environment facility communications terminals 303, one or more controlled-environment facility smart terminals 304, and one or more personal computer wireless devices 305. In the illustrated example, the telephone 302 can be a digital telephone, such as implementing VoIP communications, or another PSTN telephone, or the like. Likewise, controlled-environment facility communication terminal 303 can be a digital telephone, such as implementing VoIP communications, or PSTN communications, or the like. In accordance with embodiments of the present systems and methods, controlled-environment facility communication terminal 303 may also employ an integral, solid-surface keypad, which may be defined in, and by, a surface of a housing of controlled-environment facility communication terminal 303 (e.g., printed, embossed, braille imprinted, or the like). This keypad may be configured to be used to initiate, or otherwise enable, PSTN and/or VoIP call functions, in accordance with embodiments of the present systems and methods. That is, controlled-environment facility communication terminal 303 may include electronic (voice, video, etc.) communications functionality, using the integral, solid-surface keypad and a handset, or alternatively speaker(s) and a microphone, through data, electronic communications support provided by controlled-environment facility communication processing system 301.

Smart terminal 304 may include a display (e.g., a touch-screen display or other electronic display), camera (e.g., a webcam), and handset. The smart terminal 304 can enable telephone calls via the traditional telephone handset. The smart terminal 304 may further include audio and videoconferencing capabilities, which may enable residents to participate in video visitation sessions with non-residents of the controlled-environment facility 300 via video call, secure online chat, etc. The smart terminal 304 can enable other forms of communication, such as emails, text messages, etc. A smart terminal 304 may be disposed in a visitation room, in a pod, kiosk, etc. Additionally, or alternatively, smart terminals 304 may be deployed in a visitation center or the like, remote from, or otherwise outside, controlled-environment facility 300. The personal computer wireless device 304 can be or include a tablet computer, laptop computer, smartphone, personal digital assistant, media player, e-book reader, and/or another portable or wireless device. The personal computer wireless device 305 can enable telephone calls, videoconferencing, emails, text messaging, and/or other communication formats.

Additionally, communication processing system 301 is connected to one or more docking stations 306 that are adapted for personal computer wireless devices 305. Docking station 306 may be directly or wirelessly coupled to personal computer wireless devices 305 to provide data and/or power connections. Users may connect their personal computer wireless devices 305 to a docking station 306 for charging and/or to access additional features or functionality that are not available on personal computer wireless devices 305 alone. Additionally, as illustrated, telephone 302 may, in accordance with embodiments of the present systems and methods, be coupled to controlled-environment facility communication processing system 301, via docking station 306, as discussed in greater detail herein.

In accordance with embodiments of the present systems and methods, docking stations 306 may also act as a controlled-environment facility communications terminal, such as by providing provide PSTN and/or VoIP communication functionality, such as when a personal computer wireless device is not docked therein. As described above, an integral, solid-surface keypad may be defined in, and by, a surface of docking station 306's housing. In accordance with embodiments of the present systems and methods, docking station PSTN and/or VoIP communication functionality, may be employed when personal computer wireless device 305 is not held in the docking station, using the docking station keypad and handset, or alternatively speaker(s) and microphone of docking station 306, through controlled-environment facility communication processing system 301 electronic communications support.

Similar to as described above, the keypad of controlled-environment facility communication terminal 303 or docking station 306 may include, beyond zero to nine digit keys, a separate loudness control, which may, such as in accordance with ADA requirements, or the like, offer there or move volume settings for phone calls, or the like. The keypad may comprise raised numbers and/or letters, braille numbers and/or letters, etc. and/or provide haptic feedback to activation/selection of a key of the keypad, such as by touching of the key, such as, for example, in further ADA compliance. This feedback may be vibration, a responsive (counter) impact (emulating a button push), an audible sound, illumination of a light associated with the keypad or digit, or the like. The solid-surface communication terminal or docking station integral keypad may employ ultrasonic transducers, such as described above, deployed in conjunction with the keypad, such as mounted on a back surface of the communication terminal or docking station housing surface defining the keypad, to detect contact with the keypad by a finger, prosthetic, or the like. Alternatively, or additionally, the keypad of controlled-environment facility communication terminal 303 or docking station 306 may be an inductive touch keypad with non-moving inductive touch buttons on a flat (metal) surface of the communication terminal or docking station housing that, as described above, relies on deflection of the housing surface, without the metal contacting the sensor disposed beneath.

Controlled-environment facility communication terminals 303, smart terminals 304 and docking stations 306 may be connected to communication processing system 301 by a single pair of low-voltage wires 307, such as telephone wires or a twisted pair of copper wires. For example, docking station 306 may be coupled to a network of pairs of low-voltage wires to provide PSTN and/or VoIP communications functionality via controlled-environment facility communication processing system 301 electronic communications support.

Communication processing system 301 may include an extended signaling and electrical powering system 308 that provides electrical power and/or communications to devices 303, 304, 306 over a network of single pairs of low-voltage electrical wires (e.g., telephone wires) 307. In various embodiments, extended signaling and electrical powering system 308 may operate as a “front end” configured to filter DC and/or AC current(s) on a transmission channel to separate these signals and to pass the DC current through a low-pass filter (LPF). Extended signaling and electrical powering system 308 may also provide a high frequency (out-of-band) signaling capability isolated from the DC and audio channels by a high-pass filter (HPF) via signal transceiver and controller (STC) module 309. Additionally, or alternatively, system 308 may provide an audio channel (e.g., in the speech frequency range) for (PSTN) telephony communications isolated from the DC path by a band-pass filter (BPF). As such, power source module 310 may be configured to deliver at least 40-60 mA or more to devices 303, 304, 306 (instead of the typical 25 mA current). Alternatively, in accordance with some embodiments of the present systems and methods, the docking station may be coupled to communication network processing communication system 301 over a plurality of pairs of low-voltage wires, such as an Ethernet cable. At least some of such a plurality of pairs of low-voltage wires may provide a data connection, such as for VoIP call functions, or the like, and at least some of the plurality of pairs of low-voltage wires have an electrical current sufficient to power the personal computer wireless device, and charge its battery. Such power may be provided over these pairs of Ethernet cable wires in accordance with a PoE protocol, as noted.

Under the control of communication processing system 301, the resident communication devices (e.g., devices 302-306) of the controlled-environment facility 300 may be capable of communicatively connecting to an outside communication device, such as a device of a non-resident of the controlled-environment facility 300. The resident communication device may be communicatively coupled to an outside communication device through the communication processing system 301 to enable communications via, for example, calls, videoconferences, emails, text messaging, online chats, etc. As illustrated, the resident communication devices (e.g., devices 302-306) are communicatively coupled to the communication processing system 301. The communication processing system 301 includes a switch 311 that communicatively couples the communication processing system 301 to a PSTN 312. Remote telephone devices 313 are communicatively coupled to the PSTN 312. Hence, a resident communication device (e.g., device 302-306) may be communicatively coupled to the wireless mobile telephone and/or the landline telephone 313 via the communication processing system 301, the switch 311, and the PSTN 312.

The communication processing system 301 also includes a router 314 that communicatively couples the communication processing system 301 to a data network 315, such as a Wide Area Network (WAN), Local Area Network (LAN), the Internet, and/or a combination thereof. A digital telephone 316, a mobile computing device 317 (e.g., a mobile smart telephone, tablet, etc.), and a personal or laptop computer 318 (e.g., with a camera 319) are communicatively coupled to the data network 315. Hence, a resident communication device (e.g., device 302-306) may be communicatively coupled to the digital telephone 316, the mobile computing device 317, and/or the personal or laptop computer 318 via the communication processing system 301, the router 314, and the data network 315. A network connection between a resident communication device and an outside communication device through the data network 315 may be established and supported by an organization or commercial service that provides computer services and software for use in telecommunications and/or VoIP, such as SKYPE®. Alternatively, the controlled-environment facility 300 and/or the destination may use videoconferencing equipment compatible with ITU H.323, H.320, H.264, and/or V.80, or other suitable standards.

In addition to providing certain communication operations, communication processing system 301 may permit processing of communications to restrict aspects of communications and/or to obtain information from communications. As illustrated, an Administration and Management System (AMS) 320 maintains a database 321, and the AMS 320 is communicatively coupled to the communication processing system 301. The AMS 320 may be implemented by one or more computer systems. The AMS 320 may be co-located with and/or located remotely from the communication processing system 301. The AMS 320 may store account information corresponding to each resident of the controlled-environment facility 300 in the database 321. The communication processing system 301 may access account information of a resident from the AMS 320 (and the database 321) when processing a communication from that resident.

As an example, in the context of a correctional facility, the database 321 may include as account information for each resident the resident's Pre-Approved Contact (PAC) list and Resident Profile Data (RPD) information. The PAC list may include identities, devices, phone numbers, etc. of non-residents with whom the resident is permitted to communicate (e.g., a whitelist) or with whom they are prohibited from communicating (e.g., a blacklist). The RPD information may include, for example: balances for inmate trust and calling accounts; trial schedule; conviction data; criminal record; sentencing data, such as time served, time remaining to be served, and release date; cell and cellmate assignments; inmate restrictions and warnings; commissary order history; telephone call history; call recordings; known or suspected gang or criminal affiliations; known or suspected affiliates, accomplices, or gang members; and/or any other information that may be relevant or useful to correctional facility staff to house and maintain inmates.

When a resident attempts to initiate a communication, such as a telephone call, videoconference, etc., through a resident communication device (e.g., device 302-306), the resident may be prompted by the communication processing system 301 to provide identification information, such as a PIN, RFID, and/or biometrics (e.g., a voice sample, facial image, fingerprint, etc.). The identification information may be provided through the resident communication device and/or a media capture device 322 communicatively coupled to the communication processing system 301. The media capture device 322 may be part of an existing security surveillance infrastructure within the controlled-environment facility 300 or may be a device installed specifically for use with controlled-environment facility communication terminal 303 and/or docking station 306. In other cases, a media capture device 322 may be installed in physical proximity to resident communication devices (e.g., in a visitation room or in the same pod, wing, etc.) but be nonetheless distinct from those communication devices. For example, a PIN may be input through a keypad of the resident communication device (e.g., a punch pad, touch screen pad, virtual or physical keypad). Further, as an example, biometrics like a voice sample may be provided through a microphone of the resident communication device and/or a microphone of a media capture device 322. Similarly, as an example, a facial image may be provided by a camera of the smart terminal 304, personal computer wireless device 305, docking station 306, and/or by a camera (e.g., still capture and/or video camera) of the media capture device 322. With the identification information, the communication processing system 301 can compare the identification information against account information stored in the database 321 to identify which resident is initiating a communication and which corresponding account information to use to process the communication. For example, a PIN provided through the resident communication device can be compared to a PIN stored as account information, and/or a biometric sample can be compared to a corresponding biometric signature stored as account information.

In some examples, with the account information identified, the communication processing system 301 may attempt to ensure that the resident's communications (e.g., telephone calls, videoconferences, etc.) are performed only with non-residents whose identities, devices, phone numbers, etc. are listed in that resident's PAC list stored on the database 321. The communication processing system 301 may prohibit attempts to initiate communication with a non-resident whose identity, device, phone number, etc. is not included in the PAC list.

A monitoring system 323 may be used by authorized personnel to access on-going (i.e., real-time) and/or concluded communications for monitoring and/or investigative purposes. Alerts may be transmitted to the monitoring system 323 when significant volume level changes are detected by the communication processing system 301. Further, the monitoring system 323 may enable querying the database 321 via the communication processing system 301 for information contained in call detail records, recorded communications, etc. Access to communications and/or playback of communications may be enabled by the monitoring system 323.

Communication processing system 301 may, in addition to supporting data, voice and video communications, monitor the handset speaker and microphone loop current sensors (223 and 224) to monitor loop current in the handset speaker and/or microphone to determine if the handset speaker and/or the microphone are functional.

In accordance with some embodiments of the present systems and methods, a communication system may include communication processing system 301 configured to support data, voice and video communications and controlled-environment facility communication terminal 303 or docking stations 306 coupled to the communication processing system, wherein the docking stations not only selectively hold personal computer wireless devices and provide power and data connections to personal computer wireless devices 305, as discussed above, but also include PSTN and/or VoIP communications functionality, particularly when a personal computer wireless device is not docked therein. Likewise, controlled-environment facility communication terminal 303 include PSTN and/or VoIP communications functionality. In such embodiments, controlled-environment facility communication terminal 303 may include a keypad configured to initiate, or otherwise enable, PSTN and/or VoIP call functions, and/or docking station 306 may include a keypad configured to initiate, or otherwise enable, PSTN and/or VoIP call functions, particularly when a personal computer wireless device is not docked therein.

In accordance with such embodiments, docking station 306 may be configured to disable such PSTN and/or VoIP functions of the docking station when a personal computer wireless device 305 is held in the docking station. In accordance with further embodiments a VoIP communication in progress on personal computer wireless device 305 may be swapped to the docking station VoIP communications functionality upon the personal computer wireless device being placed in or on the docking station by handoff of VoIP signaling from the personal computer wireless device to the docking station.

Additionally, in accordance with such, or other, embodiments, another docking station (not shown), a PSTN or independent VoIP phone (302 b), another controlled-environment facility communication terminal (not shown), another smart terminals (not shown), or the like, may be coupled to communication processing system 301, via docking station 306. (A) further docking station(s) (not shown), further controlled-environment facility communication terminal(s) (not shown), (a) further PSTN or independent VoIP phone(s) (not shown), further smart terminal(s) (not shown), or the like may be coupled to the communication processing system, via this other docking station (not shown), other controlled-environment facility communication terminal (not shown), other PSTN or independent VoIP phone (302 b), other smart terminal (not shown), or the like.

Personal computer wireless device 305 may communicate with communication processing system 301 over an RF interface, such as by connecting to a Wi-Fi access point 324. Alternatively, personal computer wireless device 305 may communicate with communication processing system 301 over a wired connection using docking station 306. Depending upon the network traffic and the type of wireless and wired networks, data transfers to/from personal computer wireless device 305 may have more bandwidth and faster speeds when attached to docking station 306.

In a controlled-environment facility, docking station 306 may provide advantages such as controlling the operation of features and functions of personal computer wireless devices 305. For example, if personal computer wireless device 305 has a camera, the operation of that camera may normally be disabled for privacy and safety reasons so that pictures of the facility or other residents are not stored or transmitted outside the facility without facility authorization or approval. However, when personal computer wireless devices 305 is connected to docking station 306, then the camera may be activated since the field of view of the camera on a docked device is known, and the docking station can be positioned to ensure that field of view does not cover any sensitive areas. Additionally, docking station 306 may be placed in an area that is visible to and monitorable by the facility staff.

A further benefit of providing docking station in a controlled-environment facility is the ability to provide on-demand charging at any time using the docking station 306. This eliminates the need to have a staff member charge the personal computer wireless device 305 for a resident. In many personal computer wireless device deployments in controlled-environment facilities, the personal computer wireless devices are collected at the end of the day to be recharged overnight. Accordingly, if a personal computer wireless device's battery runs down during the day, a user would be unable to use the personal computer wireless device unless a docking station 306 was available.

When personal computer wireless device 305 is attached to docking station 306, the user may be able to access certain additional devices that are not available to personal computer wireless device 305 by another connection. For example, docking station 306 may be connected to printer 325, scanner 326, local storage/memory 327, and/or cloud storage 328. Docking station 306 may provide an authenticated and secure connection to personal computer wireless device 305, which allows applications on personal computer wireless device 305 to access printer 325, scanner 326, local storage/memory 327, and/or cloud storage 328. This would allow the user to print or scan documents, or to store data in a local memory in a cloud-based storage application (e.g., Dropbox, OneDrive, Google Drive, SecureCloud). Docking station 306 may also allow applications on personal computer wireless device 305 to access media capture devices 322.

It will be understood that the embodiment illustrated in FIG. 3 is merely one system that can adapted for use with a docking station. However, those of ordinary skill in the art will further understand that the docking station disclosed herein may be used in other configurations and systems. In view of the low power capabilities described herein, which allows power communications and data to be passed across a single pair of low-voltage wires (e.g., telephone cables, a twisted pair of copper wires), the docking station can be deployed in any location having an existing two-wire communication network or where such a network can be installed. Examples include the public switched telephone network, single-user circuits on a telephone communication system, and telephone lines used to deliver landline telephone service and/or digital subscriber line (DSL) service to premises. A single pair of wires may be twisted or untwisted, and shielded or unshielded. However, untwisted and unshielded pairs of wires may be subject to interference and crosstalk. In an example embodiment, a docking station as disclosed herein may be installed in place of an existing pay telephone or phone booth in a public, private, or restricted location. Furthermore, it will be understood that the docking station disclosed herein may be used in any location or facility in other embodiments or deployments and that the docking station is not intended for use only in controlled-environment facilities.

In some embodiments, I/O interface 430 may perform any suitable protocol, timing or other data transformations to convert data signals from one component (e.g., system memory 420) into a format usable by another component (e.g., processor 410). In some embodiments, I/O interface 430 may include support for devices attached through various types of peripheral buses, such as a variant of the Peripheral Component Interconnect (PCI) bus standard or the Universal Serial Bus (USB) standard, for example. In some embodiments, the function of I/O interface 430 may be split into two or more separate components, such as a north bridge and a south bridge, for example. In addition, in some embodiments, some or all of the functionality of I/O interface 430, such as an interface to system memory 420, may be incorporated into processor 410.

Network interface 440 may be configured to allow data to be exchanged between computer system 400 and other devices attached to a network, such as other computer systems, or between nodes of computer system 400. In various embodiments, network interface 440 may support communication via wired or wireless general data networks, such as any suitable type of Ethernet network, for example; via telecommunications/telephony networks such as analog voice networks or digital fiber communications networks; via storage area networks such as Fiber Channel SANs, or via any other suitable type of network and/or protocol.
